Diagnosis of disease of the brain is largely a matter of approximation, that is, of guesswork. The person who has had experience in guessing is more likely to be right than a novice, but oftentimes the expert misinterprets all the signs. To be sure there are certain areas of the brain that have their definite functions—the precentral convo- lution, the angular gyrus, the middle of the left first tem- poral convolution, and so forth; but when such areas be- come diseased by chronic inflammatory processes, by tumor formation or by slowly developing vascular lesion, the symptoms that result may be the same in each of them and the clinical manifestations of irritation or destruc- tion of such areas caused by one of these pathological processes are not to be distinguished from those caused ‘by another quite dissimilar in nature. It, therefore, be- comes necessary to distinguish them by other means, and here looms up a second difficulty. The general symptoms of cerebral disease have a close similarity, even those$
